Description

Technical Field

[0001] This invention relates to the field of intelligent gateway PLC data acquisition and configuration technology, specifically to a method, apparatus, intelligent gateway, device, and medium for configuring a PLC data acquisition point table. Background Technology

[0002] Currently, most PLC data acquisition point configuration solutions on the market involve pre-configuring the PLC data acquisition point table locally using existing configuration tools or remote management platforms. Users then manually add each data acquisition point one by one. Since the PLC data acquisition point table configuration file often contains tens of thousands of data acquisition points, configuring these points takes a considerable amount of time, ultimately generating a single PLC data acquisition point table file containing all the data for the entire smart gateway. After the PLC data acquisition point table file is generated, it needs to be transmitted to the smart gateway one by one over the network until the smart gateway has received all of them. This is especially problematic when users transmit the file to the remote smart gateway via a remote management platform. Due to the large amount of data, the number of interactions between the smart gateway and the remote management platform is also frequent, resulting in a lengthy configuration process that consumes significant bandwidth and is also time-consuming. Meanwhile, when users configure the PLC data acquisition point table on the remote smart gateway through the remote management platform, the time spent interacting between the smart gateway and the remote management platform is even longer when the communication latency is large. When the communication time exceeds the preset timeout, the configuration failure will be triggered and the retransmission mechanism will be started, which will lead to problems such as poor stability, low configuration efficiency, poor usability, and poor user experience.

[0003] In view of the above, this application is hereby submitted. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a configuration method, device, smart gateway, equipment and medium for PLC data acquisition point tables, which can effectively solve the problems of high data consumption, long time consumption, poor stability, low configuration efficiency, poor practicality and poor user experience in the existing PLC data acquisition point table configuration schemes.

[0007] Determine whether the point table configuration file is continuous based on the parsed text;

[0008] When it is determined that the point table configuration file is continuous, the parsed text is processed to generate a first PLC acquisition point table corresponding to the point table configuration file;

[0009] When it is determined that the point table configuration file is discontinuous, the parsed text is processed to generate a second PLC acquisition point table corresponding to the point table configuration file.

[0010] Preferably, the parsed text includes a data ID prefix, register type, register starting address or a list of register starting addresses, data type, and number of samples.

[0011] Preferably, when it is determined that the point table configuration file is continuous, the parsed text is processed to generate a first PLC acquisition point table corresponding to the point table configuration file, specifically as follows:

[0013] The increment of the PLC acquisition point table is determined based on the data type described;

[0014] Based on the number of points in the first point table and the increment, a suffix is ​​added to the prefix of the data ID sequentially, and the starting address of the register is incremented sequentially with the increment as the step value to generate the first PLC acquisition point table corresponding to the point table configuration file.

[0015] Preferably, when it is determined that the point table configuration file is discontinuous, the parsed text is processed to generate a second PLC acquisition point table corresponding to the point table configuration file, specifically as follows:

[0016] The final number of second points to be collected by the PLC acquisition point table is determined based on the number of acquisition points mentioned above.

[0017] Based on the register start address list and the number of points in the second point table, multiple data IDs and multiple register start addresses corresponding to the data IDs are generated sequentially.

[0018] A second PLC acquisition point table corresponding to the point table configuration file is generated based on each of the data IDs and the starting address of each of the registers.

[0019] This invention also discloses a method for configuring a PLC data acquisition point table, including:

[0020] Obtain relevant information for a PLC acquisition point and generate the corresponding point table configuration file;

[0021] When the network connection status is detected to be normal, the point table configuration file is sent to the smart gateway.

[0023] The parsing unit is used to receive the point table configuration file sent by the remote management platform, and parse the point table configuration file to generate parsed text, wherein the point table configuration file is a configuration file for a PLC acquisition point.

[0024] A continuity determination unit is used to determine whether the point table configuration file is continuous based on the parsed text;

[0025] A continuous point table generation unit is used to process the parsed text when it is determined that the point table configuration file is continuous, and generate a first PLC acquisition point table corresponding to the point table configuration file.

[0026] The discontinuous point table generation unit is used to process the parsed text when it is determined that the point table configuration file is discontinuous, and generate a second PLC acquisition point table corresponding to the point table configuration file.

[0032] The present invention also discloses a readable storage medium storing a computer program that can be executed by a processor of the device in which the storage medium is located, to implement the configuration method of the PLC acquisition point table as described in any of the above claims.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] This invention discloses a method, apparatus, intelligent gateway, device, and medium for configuring a PLC data acquisition point table, which at least partially addresses the shortcomings of existing technologies.

[0041] Please see Figure 1The first embodiment of the present invention provides a method for configuring a PLC data acquisition point table, which can be executed by a data acquisition point table configuration device (hereinafter referred to as the first configuration device), specifically by one or more processors within the first configuration device, to achieve the following steps:

[0042] S101, Receive the point table configuration file sent by the remote management platform, and parse the point table configuration file to generate parsed text, wherein the point table configuration file is a configuration file for a PLC acquisition point;

[0043] S102, determine whether the point table configuration file is continuous based on the parsed text;

[0044] In this embodiment, the first configuration device may be a smart gateway, which can communicate remotely with a remote management platform to receive point table configuration files sent by the platform. The remote management platform may be a smartphone, a smart computer, or other smart devices. Furthermore, the smart gateway may communicate with a lower-level machine to obtain data collected and sent by the lower-level machine (e.g., a PLC).

[0045] Current PLC data acquisition point configuration solutions on the market involve a large amount of data and frequent interactions between the smart gateway and the remote management platform, resulting in a lengthy configuration process that consumes both bandwidth and time. Furthermore, when users configure PLC data acquisition points on remote smart gateways via the remote management platform, the interaction time between the smart gateway and the remote management platform is even longer when communication latency is high. If the communication time exceeds the preset timeout, configuration failure is triggered, initiating a retransmission mechanism. This leads to poor stability, low configuration efficiency, poor usability, and a poor user experience.

[0046] In this embodiment, the parsed text includes a data ID prefix, register type, register starting address or a list of register starting addresses, data type, and number of samples.

[0047] Specifically, in this embodiment, after receiving the point table configuration file sent by the remote management platform, the first configuration device parses the point table configuration file to generate parsed text; and determines whether the parsed text contains a register start address or a list of register start addresses. If it contains a register start address, it means that the collected register data blocks are continuous; if it contains a list of register start addresses, it means that the collected register data blocks are not continuous.

[0048] S103, when it is determined that the point table configuration file is continuous, the parsed text is processed to generate a first PLC acquisition point table corresponding to the point table configuration file;

[0049] Specifically, step S103 includes: determining the final number of the first point table that the PLC acquisition point table needs to acquire based on the number of acquisitions;

[0050] The increment of the PLC acquisition point table is determined based on the data type described;

[0051] Based on the number of points in the first point table and the increment, a suffix is ​​added to the prefix of the data ID sequentially, and the starting address of the register is incremented sequentially with the increment as the step value to generate the first PLC acquisition point table corresponding to the point table configuration file.

[0052] The existing PLC data acquisition point table configuration scheme requires manual configuration for each data point when acquiring a continuous segment of data from a PLC DB register data block, ultimately generating a point table configuration file. This file is transmitted over the network and sent to the smart gateway. After receiving the complete configuration file, the smart gateway reads the raw data from the file and saves it, thus completing the entire configuration process. Table 1 shows the continuous point table configuration file sent by the existing PLC data acquisition point table configuration scheme.

[0053] Table 1:

[0054] Data ID Register type Register address Data types DB0 DBn_DBW 0 WORD DB2 DBn_DBW 2 WORD DB4 DBn_DBW 4 WORD DB6 DBn_DBW 6 WORD DB8 DBn_DBW 8 WORD ... ... ... ... DBn DBn_DBW n WORD

[0055] Specifically, in this embodiment, taking the collection of a segment of continuous data from a PLC DB register data block as an example, after receiving the point table configuration file sent by the remote management platform, the data content inside is parsed to quickly generate the collection point table required by the user; wherein, the point table configuration file is a configuration file for a PLC collection point, and the point table configuration file is shown in Table 2:

[0056] Table 2:

[0057]

[0058] First, the number of data points to be collected is determined by the number of data acquisitions. Then, the increment, or step size, is determined by the data type. For example, if the data type is DWORD, the data width is 2 bytes, so the increment is 2. Finally, based on the number of data points and the increment, a suffix is ​​added sequentially to the data IDs. For example, the first data ID is DB0, the second is DB2, the third is DB4, and so on. The register addresses are also incremented sequentially by 2. For example, the first register address is 0, the second is 2, the third is 4, and so on, to generate the final data point table to be collected, which is the first PLC data acquisition point table corresponding to the data point configuration file. The first PLC data acquisition point table is shown in Table 3.

[0059] Table 3:

[0060] Data ID Register type Register address Data types DB0 DBn_DBW 0 WORD DB2 DBn_DBW 2 WORD DB4 DBn_DBW 4 WORD DB6 DBn_DBW 6 WORD DB8 DBn_DBW 8 WORD ... ... ... ... DBn DBn_DBW n WORD

[0061] S104, when it is determined that the point table configuration file is discontinuous, the parsed text is processed to generate a second PLC acquisition point table corresponding to the point table configuration file.

[0062] Specifically, step S104 includes: determining the final number of second point tables that the PLC acquisition point table needs to acquire based on the number of acquisitions;

[0063] Based on the register start address list and the number of points in the second point table, multiple data IDs and multiple register start addresses corresponding to the data IDs are generated sequentially.

[0064] A second PLC acquisition point table corresponding to the point table configuration file is generated based on each of the data IDs and the starting address of each of the registers.

[0065] When the data in a PLC DB register data block is discontinuous, the existing PLC data acquisition point table configuration scheme uses essentially the same configuration method as the continuous configuration method described above, ultimately producing a point table file with scattered data points and a large amount of content. The discontinuous point table configuration file sent by the existing PLC data acquisition point table configuration scheme is shown in Table 4:

[0066] Table 4:

[0067] Data ID Register type Register address Data types DB0 DBn_DBW 0 WORD DB4 DBn_DBW 4 WORD DB10 DBn_DBW 10 WORD ... ... ... ... DBn DBn_DBW n WORD

[0068] Specifically, in this embodiment, taking the discontinuous data of a certain PLC DB register data block as an example, after receiving the point table configuration file sent by the remote management platform, the data content is parsed, and the required collection point table can be quickly generated according to preset rules; wherein, the point table configuration file is a configuration file for a PLC collection point, and the point table configuration file is shown in Table 5:

[0069] Table 5:

[0070]

[0071] First, the number of data points to be collected is determined by the number of data acquisitions. Then, data IDs are generated sequentially using the register start address list and the number of data points (e.g., the first data ID is DB0, the second is DB4, the third is DB10, and so on), along with the corresponding register start addresses (e.g., the first register address is 0, the second is 4, the third is 10, and so on). This generates the final data point table to be collected, which corresponds to the second PLC data acquisition point table in the data point configuration file. The second PLC data acquisition point table is shown in Table 6.

[0072] Table 6:

[0073] Data ID Register type Register address Data types DB0 DBn_DBW 0 WORD DB4 DBn_DBW 4 WORD DB10 DBn_DBW 10 WORD ... ... ... ... DBn DBn_DBW n WORD

[0074] Please see Figure 2 The second embodiment of the present invention provides a configuration method for a PLC data acquisition point table, which can be executed by a PLC data acquisition point table configuration device (hereinafter referred to as the second configuration device), specifically, by one or more processors within the second configuration device, to achieve the following steps:

[0075] S201: Obtain relevant information for a PLC acquisition point and generate the corresponding point table configuration file;

[0076] S202, when the network connection status is detected to be normal, the point table configuration file is sent to the smart gateway.

[0077] In this embodiment, the second configuration device may be a remote management platform (such as a smartphone, smart computer, or other smart device). The remote management platform device can communicate remotely with the smart gateway and send point table configuration files to it.

[0078] Specifically, in this embodiment, taking the collection of a segment of continuous data from a PLC DB register data block as an example, the user only needs to configure the relevant information of a collection point in the configuration tool or remote management platform. After the point table is generated, a very small point table configuration file is generated, which is transmitted to the smart gateway via the network in a very short time; the point table configuration file is shown in Table 1.

[0079] In this embodiment, taking the discontinuous data of a certain PLC DB register data block as an example, the user only needs to configure the relevant information of a collection point in the configuration tool or remote management platform. After the point table is generated, a very small point table configuration file will also be generated. This file is transmitted to the smart gateway via the network in a very short time. The point table configuration file is shown in Table 4.

[0080] In summary, the PLC data acquisition point table configuration method is optimized for both continuous and discontinuous scenarios. This significantly reduces the configuration time spent by users when configuring tools or remote management platforms, resulting in a much smaller generated data acquisition point table file. The amount of data transmitted over the network and the transmission time are also reduced accordingly. The entire process is greatly shortened, improving efficiency and providing a better user experience. Simply put, the PLC data acquisition point table configuration method optimizes the configuration workload of configuration tools or remote management platforms, the content of PLC data acquisition point table files, and the transmission time of PLC data acquisition point table files. This not only improves the efficiency of configuring PLC data acquisition point tables for smart gateways, reducing user configuration time and providing convenience, but also reduces the amount of data transmitted over the network, saves bandwidth, optimizes interaction time, and enhances the user experience.
